To all whom' 'it may concern:

Be it known that I, MOSES E. PiERsoN, a citizen of theUnited States, residing at Emporium, in the county of Cameron and State of Pennsylvania, have inveutefla new and useful Machine for Making Filament-Supporting Stems, of which the following is a specification.

This-invention relates to a machine for making filament-supporting stems for incandescent electric lamps. l

The invention has for one of itsobjer-:ts to improve and simplify the construction and operation of machines of this character so as to be reliable and eficient in use, readily manipulated, and so designed that a single attendant can operate the machine to produce a large number of stems with great precision and despatch.

Another object of the invention is the provision of a machine of that type including a rotary carrier or spider frame provided with a plurality of heads which receive the parts of the stem and operate on them to produce the finished article through the agency of novelly arranged instrumentalities, so that the attendant has `only to assemble the parts ofthe stem, bring them into coperative Vrelation with the heaters, press or seal the fused end of the stem, and

finally remove the finished article.

With these objects in view and others, as will appear as the description proceeds, the invention comprises the 'various novel features of construction and arrangement of parts vwhich will be more fully described hereinafter and set forth with particularity in the claims appended hereto.

In the accom anying drawings, which illustrate one ems Figure 1 is'a perspective view of the machine. Fig. 2 is an enlar ed perspective .view of one of the stem-forming heads. Fig.

Similar reference characters are employed to designate corresponding parts throughout the views.

At the outset, it will be remarked that the novelty in the present invention resides in the construction of the stem-forming head and the means for operating the anchor wire holders, all the rest of the machine forming the subject-matter of my coriding application, Serial No. 533,047, ed December 14, 1909.

Referring to the drawing, andmore particularly to Fig. 1, 1 desio'nates'the supporting column or standar of" the machine which is secured to the floor by a base 2 and carries at its upper end a rotatablespidershaped frame or carrier 3 which has, in the present instance, four radial arms 4 that are provided at their extremities with rotary stem-forming heads A which receive the parts that constitute the stem and are adapted to carry the assembled parts successively in front of the .preliminary heater H and the final heater H so as to melt the glass tube or Hare to ermit the wires to be sealed in place, the said heads being rotated only while they are o posite the heaters, as will be described hereinafter more in detail.

Eaclr head A consists of a frame composed of' a base member or cross piece 5, a top member or cross iece 6 connected rigidly together by tu ular standards 7 w ich have their upper and lower ends fastened in the ends 'of the top and bot- 1 jaws 9.,and 'these jaws 20 are disposed inV tom crossmembers. Extending verticallythe lower end of the are, as clearly shown.

in Fig. 2. The shank portion `14 of .the seat lits in the opening-11 and. is held therein by. a set screwY 15, and' by `this` means the seat can be raised lor lowered to support the Hare in proper relation to the fusing dames' of the heaters. IThe body of theseat 12 vhas an upwardly-'tapering or v conical bore 161which-` terminates at the top face of the seat in an opening' 17 through which vthe achorv wire is -insertedinto the glass tube or Hare of the stem, and'spaced'from'this opening 17 are sockets 18rfo'r receiving the platinum-tipped ends' of the leading-in wires, as clearly showin in Figs. 2 and 5.

The jaws' 9 are so constructed as' to grip the Hare a at three points so as to thereby insure a firm hold, .and lfor this purpose, the ex# tremity of'one of the jaws is straight and the otheris provided with a V-shaped recess 19 Iformed by a double angular'bend ofthe jaw member. The manner of gripping the Hare. by the jaws is clearly shown in Fig. 6 .where the threeV points `of contact are shown to be approximatelylone hundred and twenty degrees a art.v The gripping facesy of the jaws are at.and parallel^w1th the `tube 'so that a rm 'hold f can be. obtained,l .thel jaws gripping the areat a pointyapp proximately midway its len h..

,The lower end of the are 1s pinched closedl by oppositely-disposed jaws 20 "dis- -posed on the cross piece 6 ofthe 'frame of the head at a pointunder the `flare-holding chambers 21 formed in the cross piece 6 at o positesidcefof theseat-reeeiving hole 11.`

e lower'ends ofthe jaw `members 22 are pivoted' at 23 on the 'cross pieee-6 sc that transverselportion's 24 of the jaws .can swing between :'t l cross piece 6, and pinch the melted flare vfrom opposite sides'to thus anchor the lead-- ""-.t5 l

ocompression-.of kthe melted'are is e holdinggjaws 9 and inginvand'lamentanchor wires.v The deimited `Vby spaced lugs 25 projecting from l S .if K t the flare.; The pivots 23-pass through bosses th'l'face of one of the-'jaws to engage the face ofthe opposite jaw., the said lug? being ed' apart ysufficiently to receive 'etween em the' flattened or. compressed end'of 26 on the lowerl endsv of vthe jawmembers,

' and extendin from the said vmembers are lugs 27 to which are pivote'd the upper ends Leonora of actua-ting rods 28. These rods move longitudinally upwardly and downwardly to cause the jaws to close and open, the .parts being so disposed that the jaws will normally remain open by'their own weight -and attached parts. The lower ends of the rods 28 are pivoted at" 29 to` lugsl 30 on a Acollar 31 which normally rests on the bottom cross piece 5 ofthe head frame, and which is secured to the upper end of a vertically :reciprocatory lifter 32y in the form of-av sleeve. The bottom cross piece 5. has a centrally-disposed depending tubular spin'- dle 33 which is rotatably mounted in a bearing 34 on the arm 4 of the carrier 3, as :shown in-Figs. 2 .and 3. Extending lonrod-like holder 35 whichhas its upper end longitudinally bored at '36, Fig. 4, to receive the anchor wire c, and the upper eX-' tremity of this holder 35- is tapered into a point 37 so 'as to engage inthe conical bore 16 of the flare seat 12 to thereby enter the said con-ical bore and direct the anchor wirev c into the lower end of the flare through the central opening 17 ofthe seat. The anchor wire holder or positioning member 35 has a stop collar 38 which normally rests on 'f the collar 31 of the pinching jaw actuating means The member 35, which' has at its lower end a head or knob 3 9 to be engagedrby a treadle mechanism. hereinafter to be described, is normally held in its normal or lowered position, as shown in Figs. 2 and '3, by its ,own weight, and it is adapted to have an initial movement independently of ing wire can be first inserted into the lower end of theflare before the pinching jaws have'completed .the closing of the end of the iare, it being understood that th'e treadle mechanism forms a common actuator for'the. Aanchor Wire placing device and the -iarepinching or'closlng device. j

The holding jaws 9 'are adapted to be manually opened for .permitting the fla-re or glass-tube for the stem to be inserted or the completed istem removed, and for this purpose, the rockjshaftsy 8 have their lower p'ends projecting below the bottom ofthe gitudinally of the lifter or 'actuator32 isa n the jaw-actuating means so that the anchorframeof the head and are equipped with levers 40 which have reversely-disposedhandles 41 )arranged at opposite sides of the for movement in -unison by a connecting bar` -42 so that the. operator can open the jaws by'pressing one-or the lother or both levers.. Interposed between the'phandle 41 of one flever and the hub or spindle 33, of the cross piece 5 is `a compression spring 43.which loperatesfto hold the.' jaws closed under' a ylelding pressure. vWhen either handle is cross'pi'ece 5, and. these levers are connected v ressed vinwardl against this sprin thejaw-carrying roc a directiontomove the jaws 9'apart, so that a flare can be inserted or the stem removed,

and upon releasing the pressed handle 41, the jaws will automatically close. The heads are rotatably mounted in'the carrier 3, and b providing a pair of handles 41,v as shown, either handle is more likely to be disposed at the frontwhere the operator can conveniently reach it, so that the turning of the head will be avoided and thus time save d. The connecting rod 42 is attached to corresponding arms, that is to sa'y, arms projecting from the same side of the frame, and these arms 'of .the levers lare provided with pivots 43" in ythe form of bolts which have apertured heads 44 through the apertures of which the ends of the connecting rod extend and lthe shank of each bolt passes through an opening 45, Figs 11 and 13, in each lever, and receives a nut 46, Fig. 2, to hold the pivot bolt in place. The connecting rod has one end 47 swiveled in the pivot bolt on one of the levers while its opposite end 4S is threaded in the pivot bolt on the other lever, and they rod has a non-circular portion 49 to be gripped by the fingers or a Wrench for turning the rod so as to change the set of the levers and hence the position of the jaws 9 so that they can be centralized with res ect to the seat 12 on which the Hare is held) by the jaws. If the jaws come to rest in Such a positionthat the flare is too Tar to one side of the seat l2, the rod '42 will be turned in a direction to adjust the jaws to a position where the Hare will be centrally disposed on the seat.

'In order to rotate the stem-forming heads A, the spindle `33 of each head has secured thereto a friction wheel 50, and when the head carrier 3 is in a position to bring the heads 'opposite the 'burners H and H',- l'riction driving wheels51 will engage the Vwheels 50 of the two heads oppositethe burners and rotate such heads continuously while the assembled parts of the Stemware supported in the heating zones of t-he'two heaters. These friction driving wheels 51 aresecured on the upper end of vertical shafts 52 rotatably mounted in bearings 53 on the air and gas pipes 54 and 55 which supply the preliminary heater and the outer section of the final heater, said pipes being secured to the standard 1. The shafts 52 are continuously driven by a belt 56 which passes around pulleys 57 on the lower ends of the shafts'and a pulley 58 on the continuously rotating main shaft 59 of the machine, which main shaft is driven in any `suitable manner. The head-holding lframe or' carrier 3 has handles 60 projecting outwardly 'from the ends of the radial arms 4 so that the operator can conveniently turn the carrier for bringing the stem arts in the Iheads successively into coperative relation with the flames.

As shown in Fig. 1, 'a treadle mechanism,

designated generally by B, is arranged to operate the anchor Wire placing element 35 of that holder which is oppositethe final yheater H. This mechanism rvlconsists o f ,a vertically-movable rod 61 having its u per end guided in a bearing block 62 cari-ieg by the air and gas pipes 54 and-55, and-this rod, which carries a weightf63-is'connected with one arm of a lever`64 `fu'lcrumed on an outstanding arm 65 on 'the standard, andthe other arm of the lever is connected by a link 66 with a treadle 67 which is fulcrumed at 68 on the floor-adjacent the base of the standard. The upper end of the elevating device er rod 61 is formed into a head 69 or equiv# alent means which is directly under the knob 39 of the anchor wire4 placing device 35, so that when the rod 61 is raised, it Will raise the device 35 and insert the anchor wire in the lower end of the flare which is softening underthe influence of the heat of the flame. The weight 63 holds the rod 61 in lowered position with the head 69 thereof out of the path of the knob 39 of the approachingy stem-forming head, and the weight also holds the treadle raised oii the floor.

The attendant operating the machine is yseated at the side diametrically opposite from the final heater and assembles the parts of'the lament-holding stem in that head A which is nearest to her. In assembling these parts, the flare lor glass tube is placed betweenl the jaws 9 which are held open by pressing the levers 40, and as soon as the flare is placed on the seat 12, the levers are released so that the jaws will close on the flare and hold the same in central position on the seat, it, of course, being` necessary to place the unilanged end of the Hare downward so as to rest on the seat. After this is done, the leading-in wires b are inserted downwardly into the flare to engage their platinum tipped ends in the Pockets 18 of the seat, as is shown in Fig. 2. The anchor wire c is next placed in the upper end of the rod or device 35, whereupon all the parts necessary for the stem are assembled. The head carrier 3 is then given a quarterA turn to bring the head holding the parts for the stem. About the timethe parts of the third stem are assembled, the Hare in the final heater will be in condition tobe closed or pinched. In order to do this, 'she presses the treadle 67 which raises the rod 61 into engagement with the anchor wire placing device and causes the `latter to bel moved upwardly a certain distance when the head 39 thereof engages the lower end of the actuating member 32. From this time, the parts 32 and 35 move together, with the result that the anchor wire 0 will be moved into the lower end ofthe fusing flare at the same vtime the jaws 20 are moved into engagement with the flarel for compressing or pinching thesame, and by this operation, the lower end of the flare will be fiattened out, asshown at D,'Fig. 15, to firmly hold the anchor and leading-in vwires in place. AS soon as this operation is completed, the attendant releases the treadle and at the same time turns the carrier 3 another step to bring the second head opposite the final burner, where the operation just described, is repeated. vWhen the head containing the i finished stem reaches a point in front of the operator, she presses the levers 4 0 to open the jaws 9l to permit the finished stem to be taken out, and in place of the finished stem, theparts for another sternV are inserted. It

will thus be seen that the various operations i can be-carried out with great despatch and l without requiring any special skill on the -part of thev operator. AWhen the treadle is released, all the parts-lifted thereby, namely, the rod 61,` the anchor wire placing device, andthe stem-pinching or closing de' vice,l are returned to normal position by gravity so that no attention lmust be given theretoby the operator except to' releasethe treadle.

[From the foregoing description, taken in connection withthe accompanying drawings, the advantages vof the construction and of the method of operation will be readily apparent to vthose skilled in the art to which the invention a-ppertains, and while I have, described the principle of operation' of the invention, together with, the apparatus which I now consider to be the bestembodiment thereof, I desire to have it understood that Y the apparatus shown is-merely illustrative,
